Can someone help me with this question [](https://codeforces.com/contest/344/problem/C) I am able to solve the question but... in the question, it is said to minimize the number of resistors used. whereas I feel that there is only one unique way to build the given resistance. am I wrong?

Write you words in lowercase letters, please.
Abusing UPPERCASE letters makes other people think you are angry or excited.
Maybe he's angry because of not getting AC, and maybe he's also excited to find out where the mistake is.. ;)

someone respond!!
Resistance of value 1 can be built by taking 4 resistors too.(Consider an element having two resistors in series, and connect two of these elements in parallel)
I think that is not allowed in the question because question saays that the ways of constructing resistance as
an element and one resistor plugged in sequence; an element and one resistor plugged in parallel.
and also for r=6/5 , answer the judge accepted is 6(if we don't consider element linked to another element ) and not 5(if we consider an element can be linked to another element )
Sorry for not reading the question correctly. Yes, there is only a unique way of constructing the given resistance.
No. It's not unique.
Eg.: n
1 ohmresistors in series will behave like 2n1/2 ohmcomponents where each component is made up of 21 ohmresistors in parallel.
